Given numbers are 770,6410

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 770,6410 is 493570.

Find LCM of 770,6410 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 5 x 77 x 641 = 493570

Therefore, the lowest common multiple of 770,6410 is 493570.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

770 x 6410 = 4935700

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

6410 : 1, 2, 5, 10, 641, 1282, 3205, 6410

10 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,6410, is 10.

Now, the common factors can be found like this.

770:2x 5x 7x 11

6410:2x 5x 641

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

= 1

Therefore, the value for common factors is 1.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 4935700/(10x1)

LCM = 4935700/10

LCM = 493570

Thus, we can understand that the LCM of 770,6410 is 493570.
